Compaction s hall be accomplished by means of a power roller of a type and weight acceptable to the Engineer. In areas inaccessible to the roller, hand tamping or hand roller will be permitted. In any case, the bituminous material shall be uniformly compacted. The Contractor shall simultaneously extend the binder and Type I-1 surface course from the project roadway into all driveways which are not constructed with Portland cement concrete for a length of 3 feet, thereby eliminating cold joints at the gutter line.
905.04 Method of Measurement.

Driveways" will be measured by the number of cubic yards of pavement actually placed in accordance with the Plans and/or as directed by the Engineer.
905.04.2 Bituminous Concrete Sidewalks and Driveways. "Bituminous Concrete Sidewalks and
Driveways" will be measured by t he number of tons of pavement material actually placed in accordance with the Plans and/or as directed by the Engineer.
905.05 BASIS OF PAYMENT. 905.05.1 Portland Cement Concrete Sidewalks and Driveways. The accepted quantities of
"Portland Cement Concrete Sidewalks and Driveways" will be paid for at the contract unit price per cubic yard as listed in the Proposal.
